The blistering Michael Jacksondocumentary premiering at Sundance will also feature angry pro-Jackson protesters, and we've learned local police are gearing up for possible confrontations.Law enforcement sources tell TMZ ... the Park City PD is aware of an anti-documentary protest being organized on social media, so cops are going to beef up their presence both inside and outside the premiere with uniformed and undercover officers.
We're told law enforcement is most concerned about disruptions taking place during the Q&A portion of the screening -- historically, that's when protesters have caused the biggest disturbances. However, we're told cops won't stop people from exercising their First Amendment rights, so long as protesters don't block sidewalks or entrances.
As you know ... the doc, "Leaving Neverland," explores alleged sexual abuse by the King of Pop, and the film is already being slammed by the late singer's estate. Despite outside pressure to pull the film, Sundance officials say it's full steam ahead.
All Sundance events have increased security -- including bag checks and bomb dogs -- but extra resources will be allocated to the MJ screening when it premieres Friday, Jan. 25.

I hate him being described as 'troubled'. He was a predator. He went out of his way to cultivate relationships with young boys and their families. He went out of his way to cultivate an image of benign childlikeness. He went out of his way to create a physical environment full of alarms and failsafes to protect himself while he molested children. He knew what he was doing was morally abhorrent, he knew it was illegal and destructive and he still used his power, persona and wealth to do it because he liked it.

Referring to him as 'troubled' in the context of his activities as a persistent, predatory child molester is like trying to add glitter to a turd.
